Skin Rejuvenation:IPL Vs. Red Light Photo rejuvenation side (30% mild improvement and 50% moderate improvement), and in all patients (100%) of the red light side (60% mild, 10% moderate, and 30% excellent improvement). For peri-oral and peri-orbital fine wrinkles, improvement was seen in 8 patients (80%) of the IPL side (60% mild, 10% moderate, and 10% excellent improvement) and 8 patients (80%) of the red light side (50% mild and 30% moderate improvement). Skin lift was seen in 7 patients (70%) of the IPL side (30% mild and 40% moderate improvement) and in 9 patients (90%) of the red light side (60% mild, 20% moderate, and 10% excellent improvement). In quantitative measure (reviscometer), all patients showed some degrees of improvement, except one patient in the IPL side who showed 1.5% decrease. The average of reviscometer number in the IPL side before and after the treatment was 234.9 and 306.5, respectively (30% improvement, p=0.007). For red light side, these averages were 220.4 and 302.9 (37% improvement, p=0.005). Thus, both sides showed significant improvement after the treatment. But, this improvement was not significantly different between the two modalities (p=0.9). We did not find any significant correlation between the improvement of reviscometer number with skin type and age, neither in the IPL side nor in the red light side. There was no significant difference in treatment compliance between the IPL and red light treatments. No cases of major complications (scar, permanent hypo or hyper pigmentation) were seen, but severe erythema without blister formation and scar was seen in 2 patients (20%) in the IPL side. No complication with the red light treatment was seen. Conclusion Rejuvenation with IPL has been performed for more than a decade, and its efficacy has been proved in several studies. In our study, 80% of the patients showed some degrees of improvement. This is quite compatible with other studies of this type. In 2008, Y H Li and his colleagues used IPL for rejuvenation in 152 Chinese women. They achieved good or excellent response in 89% of their patients (2). Hedelund et al performed a randomized controlled split face trial on skin texture and rhytids of 32 photo aged women by 3 intense pulsed light treatments with one-month intervals on one side, or no treatment on the other side. The skin texture was significantly different between the two sides of the face in 82% of them, but improvement was mild, or moderate in most of the patients and more difference was seen one month after the completion of the study. They did not find this difference for skin Rhytids (3). For the first time, we used visible red light without photosensitizer for rejuvenation. Interestingly, the result was comparable to IPL and even more efficient than IPL for nasolabial fold and for tightening and lifting of the skin. This source of light was also very easy and safe for the patients and doctors. It associated with no pain or any important complication. Although both treatments were effective in skin rejuvenation, but their effect was different. According to our results, IPL was more effective on the fine peri- oral and peri-orbital wrinkles, and red light was more effective on the nasolabial fold and skin lift. The other advantage of our study was the use of Revicometer for measuring the skin elasticity before and after the treatment. Therefore, we could evaluate the responses quantitatively in addition to comparing the photos. Except a mild pain during the IPL therapy, both procedures were well tolerable. Only two patients experienced severe erythema and burning sensation for several days in the IPL side. In the red light side, complication rate was quite ignorable. In conclusion, use of the red light is an effective, safe, and easy way for rejuvenation, and its result is comparable with conventional procedures. References 1.
